Heat transfer of Al2O3 nanofluids in microchannel heat sink
AIP Conference Proceedings, 2017Microchannel heat sink creates an innovative cooling technology to remove large amount of heat from small area. Recently, nanotechnology gain interest to explore the microchannel cooling benefits of nanofluids as working fluid. The objective of this study is to investigate the effect of heat transfer to Al2O3 nanofluids after used as working fluid in ...

Microchannel Heat Sink with Enhanced Heat Transfer Performance by Laser Process
2018 IEEE 13th Annual International Conference on Nano/Micro Engineered and Molecular Systems (NEMS), 2018The heat transfer performance of microchannel heat sink which is fabricated by Nanosecond laser machining (NLM) is investigated. The experiment data suggest that the heat transfer performance of microchannel heat sink (MHS) processed by NLM is superior to that by Deep Reactive Ion Etching (DRIE).

Flow Boiling Oscillations in Microchannel Heat Sinks
9th AIAA/ASME Joint Thermophysics and Heat Transfer Conference, 2006*† The following presents flow boiling oscillation characteristics in two silicon microchannel heat sink configurations aimed at micro/nano- spacecraft thermal management. One is a conventional heat sink with 45 parallel channels, whereas the second is similar except with cross-links at 3 locations along the channels.

Cooling Performance of Nanofluids in a Microchannel Heat Sink
ASME 2009 Second International Conference on Micro/Nanoscale Heat and Mass Transfer, Volume 1, 2009This paper describes an experimental study on microchannel heat sink performance where ZnO nanoparticle suspended fluids are used as coolant. The microchannel heat sink has 65 parallel microchannels branched out from an inlet reservoir and then collected into an outlet reservoir.

Manifold microchannel heat sinks: isothermal analysis
InterSociety Conference on Thermal Phenomena in Electronic Systems, I-THERM V, 1997Numerical analyses of manifold microchannel (MMC) heat sinks were performed. The MMC differs from a traditional microchannel heat sink in that the flow length is greatly reduced to a small fraction of the total length of the heat sink. Alternating inlet and outlet channels guide the coolant to and from the microchannels.

Analysis and optimization of electrokinetic microchannel heat sink
International Journal of Heat and Mass Transfer, 2009A mixed (electroosmotic and pressure-driven) flow microchannel heat sink has been studied and optimized with the help of three-dimensional numerical analysis, surrogate methods, and the multi-objective evolutionary algorithm. Two design variables; the ratio of the microchannel width-to-depth and the ratio of fin width-to-depth of the microchannel are ...

Forced convection heat transfer in microchannel heat sinks
International Journal of Heat and Mass Transfer, 2007Abstract This paper presents an analysis of forced convection heat transfer in microchannel heat sinks for electronic system cooling. In view of the small dimensions of the microstructures, the microchannel is modeled as a fluid-saturated porous medium. Numerical solutions are obtained based on the Forchheimer–Brinkman-extended Darcy equation for the
